An excellent drug and alcohol testing program includes a collection site that fully meets all requirements for the safety, privacy, security, and integrity of the testing site and the testing process.  Even though most transit agencies contract out their drug and alcohol testing services to various service agents (e.g., collection sites), they cannot contract away their compliance responsibilities. This session will discuss the most common challenges transit employers face in working with drug and alcohol testing sites, especially in a "post-covid" world. We will work together to determine how to respond to a variety of real-life events and circumstances and cover what practical steps can be taken to help ensure both a compliant and efficient testing process.
